Implanted glucose sensor could help diabetics

Implanted glucose sensor could help diabetics

Researchers have developed an implantable sensor that can monitor blood-sugar levels and send the data wirelessly to an external receiver. The team has used the device in pigs for over a year, and is hoping it will work successfully in humans with diabetes.

Carbon ‘buckyballs’ found in space for the first time

Carbon 'buckyballs'  found in space for the first time

Astronomers have serendipitously found soccer-ball shaped carbon molecules in the nebula around a distant, white-dwarf star. The molecules are the largest ones ever found in space, and are part of a third type of carbon–the other two being graphite and diamond.

Moss releases its spores as ‘mushroom clouds’

A type of moss called ‘Sphagnum’ has a peculiar way of launching its spores so that they rise high enough in the air to be dispersed by winds. As the spores are released from the moss’ capsules—only about a centimetre above the ground—they form tiny mushroom clouds, helping them rise at least 10 cm up in the air, a study in Science finds (doi: 10.1126/science.1190179).  Read more

UK may miss out on ‘critical opportunities to build a green economy’

The independent Committee on Climate Change (CCC) has advised the UK government to increase investment in low-carbon technologies in order to boost green, economic growth and to achieve the target of cutting greenhouse gas emissions by 80% by 2050—relative to 1990 levels. The findings were published today in a report to the Government’s Chief Scientific advisor, Sir John Beddington.

Space probe passes asteroid Lutetia

Space probe passes asteroid Lutetia

The European Space Agency’s (ESA) comet-chasing probe Rosetta has captured the first close-up images of the asteroid Lutetia (ESA, BBC). “It’s a new world discovered by Rosetta and it will keep scientists busy for years,” said Holger Sierks, the principal investigator on the Osiris camera system (BBC). At 18:10 CEST on 10 July, the probe—equipped with cameras, spectrometers, magnetic-field experiments and more—passed within 3162 km of Lutetia. The flyby itself was very brief—lasting only about a minute—as Rosetta swept past the asteroid at a speed of 15 km/s. The 400 images that were attained during the fly-by are now being  … Read more

Iran diaspora backs ‘Green Movement’ on eve of key anniversary

More than two dozen Iranian academics and scientists in the diaspora have publicly lent their support to the Iranian opposition – the so-called ‘Green Movement’ – and its de facto leader Mir-Hossein Mousavi, in a statement circulated by email (see signatories and full text below). The move comes on the eve of the 31st anniversary of the Islamic Revolution on 11 February, and expressed the academics’ solidarity with the Iranian people on a day which is expected to witness renewed protests in Iran.
